Consider a car whose position, s, is given by the table

t (sec) 0 0.2 0.4 0.6 0.8 1

s (ft) 0 0.5 1.7 3.8 6.5 9.6

Find the average velocity over the interval 0<=t<=0.2

Estimate the velocity at t=0.2

Velocity is calculated as distance over time, so the average velocity over an interval will be the total distance traveled in that interval divided by the total time taken to travel that distance.

ok that makes sense but how do you estimate the time at 0.2?

i sketched a graph and i got a line. is it the slope of that line?
